Abstract: A phase change material (PCM) heat exchanger system for a rocket or other spacecraft is described. The PCM heat exchanger utilizes phase-change material to store heat absorbed from a hot working fluid. The PCM heat exchanger may be configured as an integrated modular double brazed layout that includes folded fins to distribute heat from a working fluid (e.g., hydraulic fluid) to PCM. A modular configuration may enable a heat exchanger system to be scaled up or down by adding or removing modules to meet cooling requirements for particular rockets and their flights.

Abstract: A brazed plate heat exchanger (10) comprising a stack of heat exchanger plates (12a, 12b) provided with a pattern comprising ridges (R) and grooves (G) to form plate interspaces (13a, 13b) for fluids to exchange heat. The heat exchanger plates are provided with port openings (O1-O4) forming inlet and outlet channels (14) for the first and second fluids, wherein at least one of the first and second heat exchanger plates is arranged with a skirt to form a chamber (17) between the port opening and the plate interspaces. The chamber (17) is open to the channel (14) through a gap between at least a free end portion of the skirt and the adjacent heat exchanger plate, and the gap varies around the circumference of the channel (14) and/or a cross section area of the chamber (17) varies around the circumference of the channel (14).

Abstract: Brazing sheets, articles formed from or including brazing sheets, and methods of forming articles are provided. The brazing sheet comprises a substrate layer, an interliner layer disposed on the substrate layer, and a brazing layer disposed on the interliner layer. The substrate layer and the brazing layer comprise aluminum alloys. The interliner layer acts as a sacrificial anode and the substrate layer acts as a cathode of a galvanic circuit within the brazing sheet.

Abstract: A heat exchanger includes a roll-bond evaporator having a heatpipe channel network spanning a primary panel area and at least one secondary multiple panel area, and at least one plurality of fins joined to at least one secondary panel area. The primary panel area is configured to receive electronic circuitry, heat transfer fluid is evaporated in heatpipe channels of the primary panel area, the heat transfer fluid is condensed in heatpipe channels in the secondary panel area(s), and heat is dissipated by the fins into an ambient environment. Secondary panel areas may be bent to bound a cavity and/or assume a generally cylindrical shape. The heat exchanger may be incorporated into a small cell radio node for 5G telecommunications.

Abstract: The present invention relates to a heat exchanger comprising multiple arranged fin tubes, each of which comprises a heat transferring fin and multiple tubes integrally formed on a plate, wherein refrigerant flows through the tubes. Each of the fin tubes has a first surface forming the front surface of the fin tube and a second surface forming the rear surface of the fin tube, and has opening part which communicates with at least a side of the multiple tubes and is formed to extend through the first surface and the second surface; and the perimeters of the openings of the fin tubes adjacent to each other may be connected through a connection part such that the openings of the adjacent fin tubes communicate with each other. Therefore, there is an advantage in that refrigerant can be distributed without a separate header.

Abstract: A water heater includes an outer casing defining a longitudinal axis, an axial direction being defined as extending along the longitudinal axis. The water heater further includes a combustor for production of hot flue gases, a primary heat exchanger including a tube positioned within the outer casing, and a secondary heat exchanger including a plurality of plates coupled together by brazing to form a brazed plate heat exchanger. The secondary heat exchanger includes a first set of passages defined between the plates, and a second set of passages defined between the plates and alternating with the first set of passages in the axial direction. The primary and secondary heat exchangers are in fluid communication such that the flue gases flow through the second set of passages before being exhausted, and water to be heated flows through the first set of passages to a delivery point for use upon demand.
